I guarantee if you make enough of these for long enough, your own crochety lady will just appear. We have someone who supposedly brings up complaints about "pagan idols" (garden gnomes) at every town meeting, and our town is relatively normal and boring by most standards.
I used to pick up 5 sticks of approximately equal length that were sufficiently bendable without breaking.
They can then be assembled into a nice pentagram after a few tries to stop them from falling apart and left at the side of the road.
An alternative method is to use those reed-like, long, strong "grass" to make one from a single piece instead of multiple. Those are usually smaller though
